Microsoft has made available a new Solution Accelerator to help businesses enable collaboration with external persons. Using this guidance, you can reduce or eliminate “Collaboration through E-Mail” with business partners and others which is most often un-secure and inefficient at the least. Setting SharePoint for external collaboration will also help you improve control over the data that is leaving your organization and provides a single resource for all involved in the project to have once source of accurate information.

The External Collaboration Toolkit for SharePoint is software and guidance that will help you to deploy a customizable solution built on Windows SharePoint Services 3.0 or Microsoft Office SharePoint Server (MOSS) 2007 that teams can use to collaborate securely with partners outside the firewall.
